缬草精油对夏黑葡萄保鲜作用的研究

Research on fresh keeping effect of Valeriana officinalis L. essential oil on Summer Black grape

以夏黑葡萄为试验材料,研究了不同体积分数缬草(Valeriana officinalis L.)精油对夏黑葡萄常温保鲜效果中风味品质(可滴定酸含量、可溶性固形物)、货架品质(好果率、呼吸强度、失重率)及质构品质(硬度)的影响。结果表明,缬草精油处理能显著延缓夏黑葡萄中可滴定酸含量的降低速度,提高好果率,保持可滴定酸含量与可溶性固形物含量,延长果实保鲜期,其中以0.50%的缬草精油处理效果最好。

Summer Black grape was used as experimental material,the effects of Valeriana officinalis L.essential oil of different con⁃centrations on the flavor quality(titratable acid content,soluble solids),shelf quality(good fruit percentage,absorption strength,weight loss rate)and texture quality(hardness)of Summer Black grape were studied.The results showed that the treatment of Valeriana officinalis L.essential oil could significantly delay the decrease of titratable acid content,increase the fruit quality,decrease the titrat⁃able acid content and soluble solids,and prolong the fruit storage period,the concentration of 0.5%Valeriana officinalis L.essential oil treatment effect was the best.
